' VEHICLE SEAT Application filed August 18, 1927; Serial No. 818,879.

This invention relates to vehicle seats and more particularly to meansfor adjusting the 1 claimed, having t same. One object of this inventionis to provide a seat and back adapted to move together with means foradjusting the inclined position of the back portion.

Another ob'ect is to provide a seat portion, a back hinge thereon, andmeans connected with the back for providing adjustment of the same in aplane ong'tudlnally of the axis of the vehicle. A further object is toprovide a resiliently mounted seat, a back hingedly mounted thereon andmeans pivotally secured to the seat back and the body frame, foradjusting the position of the seat back and permittmg movement of theback and seat.

These being among the objects of the present invention, the sameconsists of certain features of structure and combination of parts to behereinafter described with reference to the accompanying drawin and then1n view. a

In the accompanying drawing, which shows a suitable embodiment ofthepresent invention Figure 1 is a diagrammatic side view of a vehicle seatassemb y.

Figure 2 is a fragmentary top view of a vehicle bod showing theadjusting means for the seat back.

Figure 3'is a fragmentary sectional new of the seat back adjusting meanstaken on the line 3-3 of Figure 2.

Figure 4 is a erspective view of one of the adjusting mem ers.

This invention is used preferably in auto mobile seat constructions, butit will appear from the following description that the structure iseasily adapted for use in connectlon with any seat in which it isdesirable to adjust the position of the back relative to the seat.

As shown in the drawing, in which like characters of reference refer tolike arts, the seat cushion 8 mounted on the seat rame 9is'resilientlysupported by the coil springs 10 which are secured between the seatframe 9' and the conventional floor structure 11.

e above and ot er objects Hingedly mounted at 12 upon the seat framemounted adjusting devices which Wlll be described in detail in thedescription to follow.

As seen from the foregoing. description, no portion of the seat or back1s ri 'dly secured to a mounting and the seat an back therefore are freeto float so that jars and road shocks will not be transmitted to thesame.

As the adjusting devices for the seat back above mentioned are identicalin structure, gully one of the same will be described in de- As seen inFigures 1 and 3, a ball member 14 is secured to the back frame 13 byscrews 24. Pivotally supported by the member 14 is a strap member 15having one end portion 16 thereof cup-shaped to conform in shape w1ththe ball member 14. A clamping member 17 is provided which has an endsimilar in shape to the end portion 16 of the strap member 15 theclamping member 17 and the strap member 15 being secured together by therivets 17 to form with the ball member 14 a ball and socket joint.

A ball member 18 similar to the member 14 is mounted on the frame of thevehicle body 30 in oppositely disposed relation to the member 14. Astrap member 19, provided with a cupped end portion 20, is pivotallysecured to the ball member 18 by a clamping member 21 which is rivetedto the member 19 as at 21'. Each of the members 18, 19 and 21 may beidentical in shape, respectively, with the members 14, 15 and 17.

To facilitate adjustment of the seat back 13, themember 15 is providedwithspaced openings 22 and similarlythe member 19 is 0 29 for theopening between the seat back and 10.0

vehicle body is provided, the "o nin being readily accessible forstoring 't e ve 'cle curtains and the like.

It will be seen from the foregoing description that the structure hasqualifies of easy riding because any shocks or-jars will'be absorbed bythe coil springs. beneath the seat portion. Any movement of the seatwill be transmitted to the back, the same being hin ed to the seat anduniversally pivoted to the ody. Such structure will allow unitarymovement of the seat and back and permit the occupant to maintain at alltimes an easy and comfortable position.

Formal changes may be made in the specific embodiment of the inventiondescribed without departing from the spirit and substance of the broadinvention, the. scope of which is commensurate with the appended claims.
